Embodiment Construction

[0092] In order to further understand the invention content, features and effects of the present invention, the following examples are given and described in detail as follows.

[0093] see figure 1 , a method for extracting soil sample characteristics. According to the requirements of the specification, the drilling rig is used to obtain soil samples for the layout of the holes within the project scope, and the characteristics of the soil samples in a single borehole are identified one by one to obtain the soil layer characteristics of the boreholes within the project scope. The same soil layer boundaries in various boreholes are connected; the feature identification includes: the edge line, color, texture, and soil layer name of the soil sample are identified; including the following steps:

[0094] S1. According to the requirements of the specification, lay out the hole positions within the scope of the project, use the drilling rig to obtain soil samples in sequence, segme...

Abstract

The invention discloses a soil sample characteristic extraction method, system and information data processing terminal, belonging to the technical field of engineering geological survey, including: S1, laying holes in the target area, drilling soil samples, and dividing the soil samples into units Soil samples, and placed to take pictures; S2. Carry out edge line recognition, shape standardization correction, and soil sample parameter association on unit soil sample photos in sequence; S3. Calculate soil sample color and texture features within the unit soil sample boundary to obtain soil samples. According to the RGB and texture feature change values ​​of the sample, a dividing line is formed according to the buried depth direction, and the soil layer is divided according to the dividing line; Photos of borehole soil samples; S5, layered soil sample images formed according to the buried depth direction and boundary line of soil samples, and identify the characteristics of layered soil samples; S6, compare the results obtained based on feature matching discrimination and comprehensive judgment based on deep learning check against.

Description

technical field [0001] The invention belongs to the technical field of engineering geological survey, and in particular relates to a soil sample characteristic extraction method, system and information data processing terminal. Background technique [0002] As we all know, the map in nature is formed by the weathering, transportation and accumulation of rocks. Therefore, the composition of parent rock, weathering properties, transport process and accumulation environment are the main factors affecting the composition of soil, and the composition of soil is the basis for determining the engineering properties of foundation soil. Soil is composed of solid particles, water and gas, commonly known as the three-phase composition of soil. With the different mass and volume ratios of the three-phase substances, the properties of soil are also different. [0003] Soil sample characteristics include: soil sample burial depth range (bottom burial depth, top boundary (plate) burial de...
